BrunoLevy/learn-fpga ? reverse-engineered prompt

Build me a beginner friendly FPGA learning repo that teaches the basics step by step, starting with a simple blinking LED and moving up to a small RISC V processor and a tiny system on a chip. I want clear examples for things like an LED matrix, OLED display, serial output, and a few simple board demos, plus a guided tutorial that explains how to go from the first test to something that can run small programs.

Please make it feel like teaching material, with readable code, comments, and short explanations that help someone with a cheap FPGA board get started without needing expensive hardware. Include a minimal RISC V core and a basic system around it, and make the examples easy to run and modify. If you need to check current tool docs online for yosys, nextpnr, or common FPGA boards, go ahead and do that.
